Essays in Persuasion [EPUB ebook] 

Here are collected the croakings of twelve years—the croakings of a Cassandra who could never influence the course of events in time. The volume might have been entitled "Essays in Prophecy and Persuasion, " for the Prophecy, unfortunately, has been more successful than the Persuasion. But it was in a spirit of persuasion that most of these essays were written, in an attempt to influence opinion.
